I want to answer the question, “do essential oils expire?”.
Let’s get into it.
Essential oils are a mixture of numerous compounds characterized by the essence of aromatic plants.
Since essential oils are now readily available, what we need to know is do essential oils go bad and do essential oils expire.
If it is your first time trying an essential oil it could be more beneficial for you to have prior knowledge of everything about essential oils and not just joining the bandwagon.
Here we will take a look at how long essential oil lasts, whether will it be safe to use after a few years of lying idle, and the factors that can affect the effectiveness of your essential oils.
Do Essential Oils Expire – Why Purity Matters
Purity is the most important characteristic of essential oil and the main feature you should consider when buying one because pure essential oil brings out the full natural benefits of the plant whether for relaxation (aromatherapy) or treating a headache.
When an essential oil becomes contaminated it will lessen its effectiveness and may pose danger to your health if used continuously.
So how do you spot a low-quality one from pure essential oils?
First, a little research will assure you that the essential oil that you want to buy is of good quality. You can check out the company that manufactures it and learn how they produce, source, and test their essential oils.
If you still have doubts, here are other ways to check the purity of your essential oils.
1. Pure essential oils are stored in dark amber glass
Essential oils are usually stored in dark-colored glass containers to protect them from ultraviolet rays that can degrade their quality in the long run.
Be wary of essential oils that are stored in plastic containers which are not of pure quality because when essential oil gets in contact with plastics, it won’t take long before the plastics will start to break down. The chemical used to make the container will eventually contaminate the essential oils which of course will not be good for you.
Although amber-colored glass is more common for storage bottles, you can also choose blue, violet, or green which offers the same extent of protection.
2. Pure essential oils do not leave any residue on paper
One easy way to know if the essential oil you bought is pure is to make a ring test on a white strip of paper.
Let a drop of essential oil dry on a strip of paper, and if a visible ring appears in the paper, it means that it is not pure essential oil because essential oil is a volatile oil which means that it evaporates when dried.
3. Pure essential oils are not greasy
You can experiment if your essential oil feels greasy by rubbing a drop of it in between your fingers.
If it feels greasy, then it’s likely that it has a carrier oil. Pure essential oil does not leave any grease and absorbs quickly by the skin.
Can Essential Oils Expire?
Essential oils have natural antibacterial and antiviral properties that do not expire because they also don’t contain any water. Therefore, they don’t grow mildew, mold, and yeast.
However, they can’t last forever either because factors affect the changes in essential oils, such as oxidation.
These changes can affect the quality of your essential oil; that’s why essential oil has a shelf life.
Simply put, pure, high-quality essential oils are always diluted with a carrier oil because essential oil alone can irritate our skin due to its strength.
Thus, the shelf life of your essential oil is also dependent on the carrier oils it was diluted with.
For instance, some carrier oils like black currant and borage have a shorter shelf life and can go bad in about six months, while grapeseed and soybean oil can last up to a year.
On the other hand, coconut oil and jojoba oil can last until 6 years.
It really depends on what constitutes the essential oils that determine their shelf life and the reaction of these constituents from outside factors that affect the essential oil to go bad.
Likewise, you should need to know the contributing factors that affect its oxidation so that you can slow down the rate and extend the shelf life of your essential oils.
These factors are oxygen, light, and temperature.
If you want to be scientific with this, a thorough review of the stability of essential oils is found here.
Here Are the Three Main Elements That Give Rise to the Changing Properties of the Essential Oils.
Oxygen changes the chemical composition of essential oils as it reacts with their constituents. It is probably the biggest contributing factor to oxidation.
Oxidation happens when oxygen is present. Oxygen consumes the electrons from the key ingredients of essential oil, which changes the chemical composition of the essential oils.
However, this doesn’t necessarily mean that the essential oil is rancid or spoiled but its function or benefits will not be as good as before when you first opened the bottle.
To minimize exposure, here are some tips:
- Don’t let your essential oils sit open for a long time.
- Recap your bottles of essential oils tightly and quickly right after each use.
- If you prefer, you can re-bottle your essential oil to a much smaller bottle if you’re only using a small amount. In doing so, you limit the exposure of the entire essential oils and extend their shelf life.
Exposure of essential oils to sunlight can quickly change their chemical composition, even for a short period, because exposure to UV light triggers the reaction of oxygen-free radicals in the essential oils altering their chemical compositions and giving way to brand new ones.
Storing essential oils properly will avoid changes in their original composition. Keeping it in a cabinet away from light will be a good idea.
According to studies, ambient temperature crucially influences the stability of essential oils.
Generally, chemical reactions tend to hasten essential oils under heat and temperature variations. especially in citrus essential oils.
To prevent oxidation from happening, you can store your essential oil in your fridge but make sure that the temperature is no colder than 5 to 10 celsius.
In the summer, when it is more susceptible to heat, it is important to keep them in the fridge and take them out for about 12 hours before you use them.
This way, they can adjust to the room temperature. Give it a gentle shake to ensure the waxy particles are dissolved.
Therefore, it is wise to properly keep all essential oils from high temperatures or near heat.
How to Tell If It’s Expired?
Although pure essential oils don’t go bad as quickly as food does, they can change over time through the process of oxidation when they come in contact with outside properties like oxygen, light, and temperature. Once this happens, essential oils lose their therapeutic properties and fragrance.
Furthermore, it will be hard to determine what oils they have changed into, and it will be difficult also to find out whether or not they are safe to use.
One helpful way is to keep track of how long you have had it by marking the bottle with the date you first used it.
Here are other practical indications that your essential oils are no longer effective and may be time to toss or replace them.
- The smell of the essential oil has changed since you first opened the bottle. For instance, some citrus essential oils like lemon and grapefruit will have an unpleasant scent.
- The color has changed, or it becomes cloudy, like in the case of peppermint and chamomille
- It has changed in viscosity. It may have become thicker or thinner than it was when you first used it.
In any case, once you see these visible changes in your essential oils, you should avoid inhaling or using them on your skin. Expired essential oils may be harmful to use.
How to Prolong the Life of Essential Oils?
Most essential oils have a shelf life, and as mentioned their shelf life will be dependent on the carrier oil that it has and its chemical composition.
However, you can still extend the shelf life of your essential oils with these practical tips:
1. Avoid overexposure to oxygen
To prevent your essential oils from expiring early and to ensure their effectiveness, make sure to limit the time that it is uncapped because the longer it is uncapped, the more oxygen can penetrate into the oils.
Make sure also that the bottle of your essential oil is capped tightly as oxygen may still get in and start the oxidation process.
Essential oils are very reactive to light and promote the formation of oxygen free-radicals.
2. Keep your essential oils away from heat, direct sunlight, and any light sources as they are flammable.
It is best kept in a cool, dry place like in your kitchen cabinets or medicine cabinets.
But if you don’t have enough space to store essential oil, you can use a storage box.
You can place them in a place where the temperature is cool and make sure that you don’t leave them lying around. Re-cap it tightly and store it back in the box after use.
3. Since ultraviolet lights affect the composition of essential oil, you can use a smaller dark-colored essential oil bottle in storing because it will prevent oxygen from being trapped once it is opened.
This will help prevent early oxidation and extend the shelf life of your essential oil.
